The purpose of this study was to seek the spatial organization and prototype landscape through literature reviews, historical evidences, and field surveys for Donggwanwangmyo(東關王廟) shrine in Seoul. The results were as follows : First, the basic layout of the main buildings in Donggwanwangmyo which is the remains influenced by China had bilateral symmetry on the central axis between the north and south. Second, the Chinese forms and features were found at Jeong-jeon and middle gate in Donggwanwangmyo, and the symbolic elements of royal authority was also found in each space of Donggwanwangmyo. Third, spatial organization was classified as the entrance and the ritual area, and the entrance area was maintained by administrators and was used as the place of ritual ceremony preparation. Fourth, the original form of Donggwanwangmyo had been damaged due to the project for making urban park in the 1970s. The most of the existing trees and shrubs which are not suitable to the shrine should be removed to recover the original landscape of Donggwanwangmyo and chui-byoung(翠屛), pond, landscape facilities also needed to be restored. Fifth, Donggwanwangmyo needed to reorganize the pious atmosphere to recover of the shrine environment, and needed to be reclassified as historical site. Finally, some criticizes that Donggwanwangmyo is the result of Toadyism, but Donggwanwangmyo can be used as the valuable tourism resource through the awareness that Donggwanwangmyo was built under the situation of Joseon Dynasty, and organization and understanding that Donggwanwangmyo is a symbolic remains for the exchange between Korea and China.

Old-growth and giant tree is a nonrenewable resource with great value. The purpose of this study is to provide scientific and reasonable evaluations for the preservation and management of the old-growth and giant tree. Until now the research of old-growth and giant tree's value evaluation and authoritative index is so insufficient and imperfection. Combining with the particularity of the old-growth and giant tree, this study analyzed the main value factors of the old-growth and giant tree and objectively selected the evaluation indicators. According to the actual situation value appraisal model of the old-growth and giant tree was builded. The main value factors can be divided into economic value, cultural history, growing place, tree state, tree form, tree vigor, protection level, growth environment, tree species, tree canopy, and so on. The evaluate indicators can be selected and the indicators' weight can be calculate using analytic hierarchy process methods(AHP). Based on economic value and indicators' weight, tree's total value can be revealed. After calculation and analysis, Gyeongju Gyerim Zelkova serrata's value evaluation results is 491,503,300 won. The research results of this study can provide scientific basis and reference to the old-growth and giant trees' value appraisal and loss compensation, and arouse people's environmental awareness.

Location awareness is one of the key functionalities to build an U-city. Recently, many of works of the location-aware systems are emerging to commercially apply to on-going large-scale apartment complex based on U-city. As dwellers or cars being attached with active tags are moving in the U-city complex, the active tags periodically broadcast their own identifiers and receivers fixed along the street or in building use those information to calculate location of them. There are several issues to be considered for such an environment. The first is that the number of active tags operating in the same region are large as much as tens of thousands, and the second is that the active tags should be alive without change of batteries more than a year, hence low power consumption is very important. In this paper we propose i) a new architecture for location-aware system considering such issues, ii) technical issues to implement it using active tags, and iii) a mathematical analytic model to investigate overall performance and verify it by comparing with actual experimental results. Through the analysis we can show the theoretical boundary of the lowest packet loss rate and the maximum number of tags with acceptable performance for the systems based on active tags. The results can be applied to practical design of location-based systems of U-City projects.

This study analyzed the educational background, career, and post-retirement activities of notable bureaucrats employed at Chosun Railway Bureau during the Japanese colonial period in Korea. First, significantly, most railway bureaucrats were of Japanese origin, being specialized in railway operations and adjusted to occupation in a reserved organizational environment for a considerable time period. Second, the Japanese showed explicit eagerness to work at the Chosun Railway, which fitted their ideology of railway bureaucrats. In addition, almost 60% of the bureaucrat population had strong educational experience from Tokyo Imperial University, which is equal to the percentage of graduates from other institutions operating during the Japanese colonial period. Moreover, in the very early period of building the railway system, the demand for specialists was higher than for other jobs and divisions because of the railroad's complex infrastructure, which resulted in high job appointment rates. In a similar sense, based on a strong affiliation of bureaucrats with railways, the number of bureaucrats from Japanese Railway Worker's Bureau was higher initially because of bureaucrats from South Manchurian Railway Company. These changes essentially contributed to alteration of bureaucrats' awareness and created a more positive attitude regarding the Chosun Railway. In the meantime, as opposed to the Taiwan and Manchurian Railways, both Chosun Railway and the Taiwan Railway were operated in compliance with strong bureaucratic traditions.

Objectives: This study examined the current status of depression and related factors among children using community child center. Methods: A cross-sectional study selected children in grades 4-6 who used the Gwangju and Jeollanamdo community child center (n=224) using a convenience sampling method. General characteristics, family characteristics, children's emotional characteristics, children's school life environment and depression status were assessed using a self-reported questionnaire. Results: The average score of depression among children using community child center was 15.31±7.70 out of a total of 27. Fifty-eight (25.9%) children had depression above 22 points. Variables related to children's depression were shown as grade, subjective economic level awareness, after-school activities excluding local children's centers, presence of family members after school, and family structure. Conclusions: The depression prevalence of children using community child center was higher. Policy support such as children's psychological support programs would be needed to reduce children's depression, and community child centers are expected to be effective in reducing children's depression if continuous child psychological support services are developed for children's mental health.

It is essential that the evaluation of official development assistance (ODA) projects is conducted based on empirical research for the performance and improvement of the project. This study intended to quantitatively figure out the actual status and performance of ODA projects. The performance of the Rumpin Seed Source and Nursery Center project implemented by the KOICA was evaluated in items of relevance, efficiency, effectiveness, impact, sustainability, which are OECD Development Assistance Committee(DAC) evaluation criteria. From August 26, 2019 to August 29, 2019, a survey was conducted on 50 visitors and 54 stakeholders of the Rumpin Seed Source and Nursery Center. Through on-site survey, problems in the donation project and operation in Indonesia were identified and measures for improvement was grasped. As a result of the study, the value scored by OECD DAC evaluation criteria of the Rumpin Seed Source and Nursery Center project based on the Economic Development Cooperation Fund(EDCF) evaluation grade was evaluated as a very successful class in all items. The average score of the recognition question was 4.08 points for visitors and 4.08 points for stakeholders, and the average score for the satisfaction question was 4.37 points for visitors and 4.11 points for stakeholders, which were high overall in both groups. The main factor that affects the project awareness of the visitors was the fact that the Rumpin Seed Source and Nursery Center was created based on Korean technology, and it was confirmed that Indonesia's own items related to similar projects had a great influence on the project satisfaction. In the case of stakeholders, project support in Korea affected their recognition, and it was found that relevance, efficiency, effectiveness items had the greatest impact on the level of project satisfaction of stakeholders derived from the DAC individual evaluation results. Efforts are required to increase the main factors by reflecting the results of each item and to preserve and maintain the project. This study is significant in determining the performance of the ODA project based on empirical data, and it is believed that it can be used as basic data for supplementing and strengthening the project in the future.

Seafaring is an important occupation that requires stringent hand hygiene practices as a basic method for preventing food-borne illness and infectious diseases when the diseases occur on board. The purpose of this study is to provide fundamental data for the prevention of food-borne illness and infectious disease on the ship by investigating the level of hand hygiene practices and influencing factors. A total of 222 seafarers were surveyed at a seafarers' educational institution between July and August 2017. Their hand hygiene practice were examined by a modified method using the guidelines which are recommended by the World Health Organization, the Centers for Disease Control and Prevention, and Hand Hygiene Australia. The mean of hand hygiene practice was 47.97 out of 75 points. By category, the most frequent hand hygiene practice was measured as 4.04 on a 5-point scale as 'after working'. Factors affecting hand hygiene practices were ship tonnage relating to in job characteristics, exercise in health-related characteristics, and soap in relation to the characteristics of the hand hygiene environment on board. To improve hand hygiene among seafarers, it is necessary to raise awareness of hand hygiene among seafarers who work on small ships in particular, and to improve the systems of hand hygiene on ships with continuous education, hygiene practice evaluation and feedback.

Objective : The aim of this study was to examine the relationship between occupational stress and depression, as it is seen to be corresponding with the work characteristics of local government officials. Methods : The data of 671 local government officials who participated in this study from July to December 2015 as a part of an occupational stress management program, were analyzed retrospectively in this study. Likewise, the participants completed questionnaires, including a short form of the Korean Occupational Stress Scale (KOSS), and the Beck Depression Inventory-II (BDI-II) the results of which were evaluated and reviewed. Results : The study noted that the subscales of occupational stress related to depression were varied, according to the work characteristics of the participants, after adjusting for age and job grade. It was found that the participant's variables of job insecurity, lack of reward, organizational system and occupational climate were significantly related to the development of a depressed mood in the participant in a general sense. Notably, the factor of interpersonal conflict was significantly related to depressed mood among the general administrative group; meanwhile, lack of reward in the welfare group and insufficient job control in the technical group were significantly associated with the likelihood of developing a depressed mood in participants reviewed. In the operation and maintenance of facilities group, job insecurity was significantly related with depressed mood, whereas job demand was related more with the incidence of depression in the field work group. Conclusion : This study revealed that the influence of occupational stress on depression varied according to the occupational characteristics experienced by the participants in the work environment. These findings may be used to enhance the occupational stress management program for local government officials according to their work characteristics, to bring awareness to this issue.

This study attempts to make an empirical analysis on how mobile devices affect users in building their social relationship and if their influences are negative or positive. The purpose of this research is to explain the results by considering all the possibilities and exploring everyday lives of using mobile devices. We used the survey data from the "Research on Mobile Environment Awareness" conducted by Gyeonggi Research Institute(GRI). The main question was about the use of mobile devices and social network services (SNS) and users' opinions on using the devices. All of the 31 municipalities in Gyeonggi Province were included as a spatial range, and the final validity sample was 1,004 residents. The extent of the relationship with people is selected as a dependent variable through the multinomial logistic model and the decision tree model. As a result of the multinomial logistic analysis on the questionnaire, the characteristics of the respondents with some changes in the scope of the human relationship were found to have a significant (+) effect on conversation with family, SNS usage, residence in the rural area but not urban area, and device usage for obtaining news. The largest variable affecting the extent of relationship was the SNS usage. As the amount of SNS usage increases, the extent of the relationship also changes a lot.
